US Patent:

7920093, Apr 5, 2011

Filed:

Sep 27, 2007

Appl. No.:

11/904600

Inventors:

Gregory W. Heckler - Greenbelt MD, US
James L. Garrison - Lafayette IN, US

Assignee:

Purdue Research Foundation - West Lafayette IN

International Classification:

G01S 19/37

US Classification:

34235777

Abstract:

A method reduces consumption of computational resources in a satellite signal receiver. The method includes segmenting a sample of a received global positioning base band vector, segmenting a sample of a replica code/acquisition signal into segments corresponding in length to the segments of the base band vector, circularly correlating segments of the base band vector to zero padded segments of the code/acquisition signal to form a time domain correlation vector, inserting a portion of the time domain correlation vector in a matrix, continuing to correlate circularly the segments of the received signal sample with zero padded segments of the code signal sample until all of the segments in received signal sample have been circularly correlated, dividing rows in the matrix into blocks that are equal to a smallest increment corresponding to a bit edge, sorting the blocks from the divided rows into zero padded blocks, transforming the zero padded blocks into frequency domain columns, summing the frequency domain columns in different combinations to form a plurality of coherent integration matrices for testing possible bit edge locations and bit values.

Inventors:

James E. Garrison - District Heights MD, US

International Classification:

G07F 17/12

US Classification:

312215, 312237, 312234

Abstract:

An approach is provided to facilitate storage space rental services from a self sustaining solar powered storage locker rental system that may be remotely monitored and controlled. The apparatus includes one or more storage lockers each having respective electronic locking mechanisms. The apparatus is configured to process a request to access a storage locker and determine storage locker availability. The apparatus displays which of the one or more storage lockers is available and processes a selection of an available storage locker to generate an access message that includes a locker number, a randomly generated access code, and a duration of access indication based on a confirmed financial transaction. The apparatus also includes at least one solar energy collection unit configured to collect solar energy, and an energy storage unit configured to store the collected solar energy and supply power to the apparatus.
